Hello everyone, I was diagnosed with peripheral small fiber neuropathy in 2019. The cause was excess of Vitamin B6. It is in my feet and lower legs. Of course I quit taking the vitamin supplement that had a high level of B6. I have been able to control the pain with Alpha-Lipoic Acid 1200 mg per day taken in the morning, and Benfotiamine 150 mg per day taken before dinner, and CBD only salve every night on my feet. The tingling, burning is always worst at night and the CBD keeps my feet calm and comfortable most nights. I know for sure this all works because I have gone off for a few days and had the burning sensations return; and after 2 days of the routine I am back to good. I have tried several brands of CBD and also tried a CBD/THC combo. The one that works best for me is CBD only, made by Charlotte's Web, available for mail order online.
Also, I recommend icing the bottom of your feet in the evening before bedtime. Some days I need to do this because the day's activities made my feet hot and burning. Amazing how good the ice feels and how quickly it calms those burning nerves.
